UNITED STATES PATENT OEEicE.

JOHN B. DEEDS, OF TERRE IIAUTE, INDIANA, ASSIGNOR TO ROBERT I-I. CATLIN,OF SAME PLACE.

ANTl FRICTION COMPOUND.

SPECIFICATION forming part of Letters Patent No. 395,216, dated December25, 1888.

Application filed February 11, 1888. Serial No. 263,674. (Specimens) T0to 1071 0112, it may concern:

Be it known that 1, JOHN B. DEEDS, a citizen of the United States,residing at Terre llaute, in the county of Vigo and State of Indiana,have invented certain new and useful Improvements in Packing )ompounds;and I do hereby declare the :lollowing to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

This invention relates to certain new and useful improvements inmaterials or compounds designed as a lining or packing forstuffing-boxes journal bearings, machine joints, and similar uses.

The object of the invention is to supply a compound which shall possessthe characteristics of durability and compactness by which to render thesame of considerable value for the purposes intended.

In carrying my invention into effect I take about one pound of tallow orsimilar fatty matter, and to this I add about two ounces of beeswax orparal'line, and these are placed in any suitable vessel and heated veryhot, so as to become melted and intimately mixed. A constant stirring ofthe mixture should be kept up, and when sufficiently mixed I add aboutthree ounces of plumbago or black lead combined with an equal amount ofbrimstone, and also stir this up thoroughly. All should be kept heatedfor at least one hour, after which I add to the heated mixture aboutone-half pound of asbestus yarn or wicking combined with as much stronghemp as will absorb the heated mixture, which, when saturated andpermitted. to cool,will act to hold the mass together strongly whensubjected to a high pressure or great friction. No further mode ofcompounding is necessary:

I have used a compound thus prepared, and have found it to possess allthe requirements of a packing for stuffing-boxes, joints, and the like,and I have also found that when the fibers of asbestus and hemp havebecome thus treated the resultant compound or material may be readilytwisted or plaited into a rope of any desired size or length. \Yhen usedas a packing for stuffing-boxes, I have found it very valuable forfilling the space within the stuffing-box surrounding the metallicrindescribed and claimed in my application of even date herewith, SerialNo. 263,725; but it is evident that I am not limited tosuch use.

Having thus described my invention, what I claim as new, and desire tosecure by -Letters Patent, is r A lining or packing consisting of thefollowing ingredients in about the proportions named: one pound oftallow or similar fatty matter, two ounces of beeswax or paralfine,three ounces of plumbago combined with about an equal quantity ofbrimstone, 011ehalf pound of asbestus yarn or wicking, and strong hemp,substantially as described.

In testimony whereof I at'fix my signature in presence of two witnesses.

JOHN I3. DEEDS.
